Engine Cooling problem
1996 Chevy Blazer 6 cyl Four Wheel Drive Automatic

I just recently had this at the shop for a coolant leak. They replaced the thermostat and put new coolant in. Now the temperature gauge gets around 150 and then goes almost to 210 then back to 150 is this normal? If not what do I do to fix it?

check and make sure your coolant is full and the connector on the temp sensor is on tight. if not take it back and have the person who did the work look at it
